Disappointed in the service!!

Fed up is one word but I'm done naging sending emails just for it to be closed the next day telling me every time I'm using the wrong speedtest website or on there side it's shows it's 50 up and 50 down its been almost a year with this company and every month i have to struggle with my network and every day from 18:00 till 22:00 i can't do anything on my network and now i don't have any network connection. I had enough i will be going to the ombudsman as I'm done paying almost R800 for a service that I'm not receiving and today.
